본 발명은 음식물류 폐기물 악취 제거를 위한 UV/오존촉매의 제조방법 및 이에 의해 제조된 음식물류 폐기물 악취 제거를 위한 UV/오존촉매에 관한 것으로서, 보다 상세하게는 가정용 음식물 처리기 또는 대형 음식물처리장으로부터 배출되는 고온다습한 악취가스를 장시간 안정적으로 제거할 뿐만 아니라 고효율로 제거할 수 있는 음식물류 폐기물 악취 제거를 위한 UV/오존촉매의 제조방법 이에 의해 제조된 음식물류 폐기물 악취 제거를 위한 UV/오존촉매에 관한 것이다.
The present invention relates to a method for preparing UV / ozone catalyst for removing food waste odor, and to a UV / ozone catalyst for removing food waste odor produced by the above, and more particularly, to a high temperature discharged from a domestic food processor or a large food processing plant. The present invention relates to a UV / ozone catalyst for removing food waste odors, which can be removed stably for long periods of time, as well as to remove food waste odors with high efficiency.

일반적으로 각 가정 또는 음식점 등에서는 매일 일정량의 음식물류 폐기물이 배출되며, 이러한 음식물류 폐기물은 그대로 가축사료로 이용하거나 단순한 거름망을 통하여 섞여 있는 물기 만을 걸러낸 후 폐기시키고 있다. 이러한 음식물류 폐기물 처리 방법은 쓰레기 수량을 증대시키고, 쓰레기를 자주 버리지 않을 경우 악취를 발생시켜 주변의 공기를 오염시키므로 음식물 처리기가 사용된다.In general, a certain amount of food waste is discharged from homes or restaurants every day, and these food wastes are used as livestock feed or only mixed with water through a simple strainer and then discarded. This food waste treatment method increases the amount of waste, and if the waste is not thrown away frequently, it causes odors and pollutes the surrounding air.

보통 음식물처리기에서 발생하는 악취의 성분은 여러 종류의 가스가 복합적으로 발생하게 되며 음식물의 종류, 방치기간, 처리온도 등 그 상태에 따라 가스의 성분이 달라지며 부패나 이상발효, 즉 혐기성 발효가 일어날 경우는 인체에도 해를 미칠 수 있는 독성이 있는 고약한 냄새의 가스가 다량 방출하게 된다.The odor component that is usually generated in the food processor generates various kinds of gases, and the gas composition varies depending on the type of food, the length of the food, the treatment period, and the processing temperature, resulting in decay or abnormal fermentation, that is, anaerobic fermentation. In some cases, a large amount of toxic odorous gas can be released, which can harm the human body.

이는 음식물류 폐기물의 연속처리 과정에서 부분적으로 혐기적 조건이 형성되어 진행될수록 더욱 심한 악취가 발생하게 되며 이때 발생하는 악취 원인을 제공하는 가스는 크게 산성, 중성, 염기성으로 분리할 수 있다. 산성계 가스로는 황화수소, 메틸메르캅탄 등이 있고, 염기성계 가스로는 암모니아, 트리메틸아민 등이 있으며, 중성계 가스로는 황화메틸, 이황화메틸, 아세트알데히드 등이 있다. 이러한 악취 가스는 인체에 유해하고 대기, 환경오염의 원인이 되며 주변시설에 혐오감을 주어 그 상태가 심각하였다.This is due to the formation of anaerobic conditions in the course of continuous processing of food waste, the more severe odor is generated and the gas providing the cause of the odor generated at this time can be largely separated into acid, neutral, basic. Examples of the acid gas include hydrogen sulfide and methyl mercaptan, and basic gas includes ammonia and trimethylamine. Neutral gas includes methyl sulfide, methyl disulfide, acetaldehyde and the like. These odorous gases are harmful to the human body, cause air and environmental pollution, and have aversion to the surrounding facilities.

일반적으로 음식물 처리기용 탈취 필터에서는, 활성탄(activated carbon)을 음식물류 폐기물의 연속처리 과정에서 발생하는 악취를 제거하기 위한 필터 소재로서 사용하여 왔다. 활성탄은 일종의 숯과 같은 것으로서, 내부가 미세 공극과 같은 다공질로 되어 있어 악취 성분은 포집함으로써 오염된 공기를 정화하는데 탁월한 작용을 하기 때문이다.In general, in a deodorizing filter for a food processor, activated carbon has been used as a filter material for removing odor generated during continuous processing of food waste. Activated charcoal is a kind of charcoal, and because the inside is porous like micro-pore, it collects odor and plays an excellent role in purifying polluted air.

그러나, 활성탄의 성능은 한계가 있으며 악취 성분이 활성탄 내에 포집됨에 따라 활성탄의 미세 공극이 점점 작아지게 되는 현상이 발생한다. 그로 인해 활성탄의 탈취 효율이 감소된다는 문제점이 발생한다.However, the performance of activated carbon is limited, and as the odor component is collected in the activated carbon, a phenomenon in which the fine pores of the activated carbon becomes smaller and smaller occurs. This causes a problem that the deodorization efficiency of activated carbon is reduced.

상기와 같은 문제를 해결하기 위해, 대한민국특허공개 제10-2011-0043313호(2011.04.27.)에는 활성탄 필터 구조가 개시되어 있다. 상기 활성탄 필터 구조는 광촉매(Photocatalyst)를 활성탄 내부에 분포시켜 활성탄 내에 포집된 악취 성분을 분해함으로써 활성탄의 탈취 효율을 보다 장기간 지속시킬 수 있는 장점이 있지만, 고온다습한 음식물류 폐기물의 악취를 제거하는 효율이 높지 않은 문제가 있다.
In order to solve the above problems, Korean Patent Publication No. 10-2011-0043313 (2011.04.27.) Discloses an activated carbon filter structure. The activated carbon filter structure has a merit of distributing photocatalyst inside activated carbon to decompose odor components trapped in activated carbon to maintain the deodorization efficiency of activated carbon for a longer time, but to remove odor of hot and humid food waste. There is a problem that is not high.

본 발명자들은 상기 활성탄 필터의 문제점을 해결하기 위해, 가정용 음식물 처리기 또는 대형 음식물처리장으로부터 배출되는 고온다습한 악취가스를 장시간 안정적으로 제거할 뿐만 아니라 고효율로 제거할 수 있는 UV/오존촉매를 개발하였다.
In order to solve the problem of the activated carbon filter, the present inventors have developed a UV / ozone catalyst that can stably remove high temperature and humid odor gas discharged from a domestic food processor or a large food treatment plant for a long time, as well as with high efficiency.

It includes.

상기 단계 1은 지지체를 20~40㎚의 나노실리카 졸에 2~3시간 동안 담지한 후, 건조오븐에서 35~45℃의 온도에서 11~12시간 동안 건조하여 나노실리카 박막을 형성하는 단계이다. 상기 지지체는 제올라이트, 활성탄, 유리섬유 및 종이로 구성된 군으로부터 선택된 어느 하나를 사용할 수 있다.Step 1 is a step of supporting the support in a nano silica sol of 20-40 nm for 2 to 3 hours, and then dried for 11 to 12 hours at a temperature of 35 ~ 45 ℃ in a drying oven to form a nano-silica thin film. The support may be any one selected from the group consisting of zeolite, activated carbon, fiberglass and paper.

상기 지지체 100중량부에 대하여 나노실리카 졸이 5중량부 미만 혼합되면 코팅되는 박막의 표면이 충분하게 제공되지 못하여 지지체 표면이 노출 및 촉매결합에 필요한 실리카 박막표면이 부족하게 되는 문제가 있고, 10중량부 초과 혼합되면 지지체 공극을 막아버리는 문제가 있다.
If less than 5 parts by weight of the nanosilica sol is mixed with respect to 100 parts by weight of the support, there is a problem that the surface of the coated film is not sufficiently provided, and thus the surface of the support is insufficient and the surface of the silica thin film required for catalytic bonding is insufficient. There is a problem of blocking the support pores when the excess mixing is performed.

상기 단계 2는 상기 나노실리카 박막이 형성된 지지체를 Al(OH)3 및 TIO2 수용액에 2~4시간 동안 담지한 후, 건조오븐 70~80℃에서 5~6시간 동안 밀봉하여 반응시킨 후 개봉하고 140~150℃에서 11~12시간 동안 건조하여 광촉매 및 중간연결자 촉매를 도입하는 단계이다.Step 2 is a support on which the nano-silica thin film is formed Al (OH) 3 and TIO 2 After supporting for 2-4 hours in an aqueous solution, the reaction was sealed and dried for 5-6 hours at 70 ~ 80 ℃ drying oven and then opened and dried for 11-12 hours at 140 ~ 150 ℃ to introduce a photocatalyst and intermediate connector catalyst Step.

상기 Al(OH)3 및 TIO2 는 -O-Al-O-Ti-O- 상태로 광촉매 및 중간연결자 촉매 역할을 담당하게 된다.Al (OH) 3 and TIO 2 In the -O-Al-O-Ti-O- state will act as a photocatalyst and an intermediate connector catalyst.

상기 오존 촉매는 KI(Potassium iodide)를 사용하는 것이 바람직하며, 악취가스를 오존을 이용하여 산화분해되도록 유도하는 역할을 담당한다.The ozone catalyst is preferably used KI (Potassium iodide), and serves to induce odor gas to be oxidized decomposition using ozone.

상기 광촉매 및 중간연결자 촉매가 도입된 지지체 100중량부에 대하여 오존촉매가 3중량부 미만 혼합되면 오존분해효과가 저하되는 문제가 있고, 5중량부 초과 혼합되면 중간연결자 촉매를 도포하여 촉매역할이 저하되는 문제가 있다.
When the ozone catalyst is mixed less than 3 parts by weight based on 100 parts by weight of the support on which the photocatalyst and the intermediate connector catalyst are introduced, there is a problem in that the ozone decomposition effect is lowered. There is a problem.

상기 단계 4는 상기 촉매결합체를 소성로에서 530~800℃의 온도에서 4~6시간 동안 열처리한 후 냉각하여 UV/오존촉매를 제조하는 단계이다. Step 4 is a step of preparing a UV / ozone catalyst by heat-treating the catalyst binder for 4-6 hours at a temperature of 530 ~ 800 ℃ in a kiln.

상기 촉매결합체를 소성로에서 530℃ 미만의 온도에서 열처리하면 촉매 활성이 저하될 수 있고, 800℃ 초과의 온도에서 열처리하면 베타형 알루미나 결정체 성장의 문제가 있다.
When the catalyst binder is heat treated at a temperature of less than 530 ° C. in a calcination furnace, catalytic activity may be lowered. If the catalyst binder is heat treated at a temperature above 800 ° C., there is a problem of beta-type alumina crystal growth.
